Abstract

一种防止板处理器设备中的印刷板变形的装置(39)，包括：板传送装置(19)，该板传送装置(19)包括马达(15)和多个辊子(11、12、13、14)。单向联接器(21)连接所述马达(15)和所述多个辊子(11、12、13、14)。识别装置识别较慢的辊子并从所述马达上分离所述较慢的辊子。

Description

防止板处理器设备中的印刷板变形的装置和方法
技术领域
本发明涉及用于印刷行业的板显影处理器(plate developing processor)中的印刷板传送速度控制装置和方法。 
背景技术
印刷板显影处理器通常使用用于进入板的水平传送系统。该传送系统通常包括多个由马达驱动的辊子，且辊子被诸如橡胶的柔性材料覆盖。 
参考图1，板10进入传送系统19，沿方向18前进。板10在几对辊子11、12、13和14的辅助下传送穿过处理器。上辊子11和14接触板10的上表面，下辊子12和13接触板10的下表面。马达15转动所有的辊子(例如11、12、13和14)。在板的传送过程中，辊子被紧固在板的表面上，且辊子的转动引起板10沿方向18向前移动。该移动是通过将辊子(11、12、13、14)的角速度转换为移动板10的水平速度而实现的。 
辊子的角速度至线性的板速度的转换受到辊子与板的接触点处辊子的半径的影响。板的运动取决于施加到辊子上的压力、辊子的橡胶涂层的磨损程度，以及其他因素。由此导致的辊子半径的差异可能在板10上产生不同的力，从而导致板在处理器内变形，如变形板区域17所示。 
发明内容
简要地说，根据本发明的一方面，防止板处理器设备中印刷板变形的方法包括：在包括马达和多个辊子的板处理器设备中传送印刷板。离合器连接马达和多个辊子。较慢的辊子被识别并从马达上分离。 
结合附图，通过阅读以下详细描述，本领域技术人员将明了本发明的以上以及其他目的、特征和优点，其中，附图显示和描述了本发明的示例性实施例。 
附图说明
图1是显示现有技术的板传送系统的示意图； 
图2是显示利用离合器来控制板速从而防止板变形的板传送系统的示意图；以及 
图3是显示利用传感器和离合器来控制板速从而防止板变形的板传送系统的示意图。 
具体实施方式
在以下详细描述中，参考构成该描述的一部分的附图，其中显示了可以实施所述方法和装置的示例性的特定实施例。由于本发明的实施例的部件可以以多个不同方向定位，因此出于示例而非限制的目的使用方向术语。 
本发明解决板显影处理器中的板水平运动过程中的板变形、折叠或拉伸的问题。参考图2，离合器21被加入由马达15驱动的每个辊子，以形成配备离合器的传送系统29。可以使用的离合器21部件例如是在自行车行业中使用的那种离合器。 
所加入的离合器21将导致具有最快切线速度的辊子起作用，从而控制并驱动板20。所有其他辊子的控制将被连接到这些辊子的离合器禁止，并将导致这些辊子以前进的板20的速度转动。这将引起施加于在配备离合器的传送系统29中传送的板20上的相对的力被消除，从而防止板20变形。 
在另一个实施例中显示了使用不同类型的离合器的传送系统39(图3中)。可以使用传感器30来识别较慢的辊子或辊子对，然后该辊子或辊子对被分离。传感器30通过传感线31感测辊子(11-14)，且离合器21根据从辊子(11-14)感测的结果被控制线32控制。
